Hot roller drafting type corterra pre-oriented filament drafting and wingding device

Abstract

The invention discloses a hot roller drafting type corterra pre-oriented filament drafting and wingding device, comprising a heating drafting part which is installed in front of an installation faceplate and comprises two spinning hot roller groups i.e. a first spinning hot roller group GR1 for carrying out pre-oriented drafting and low-temperature heating on corterra filament tows and a second spinning hot roller group GR2 for carrying out low-power drafting and drafting stress eliminating on the heated corterra filament tows, wherein the first spinning hot roller group GR1 and the second spinning hot roller group GR2 are sequentially arranged along the circularly-moving direction of the tows; each spinning hot roller group is provided with a hot roller and a separator roller; and the hot rollers are perpendicular to the installation faceplate. The device disclosed by the invention has the advantages that the process requirements for the heating pre-oriented drafting of the corterra filament tows are satisfied; the construction cost of hot roller drafting type corterra pre-oriented filament drafting and wingding device is reduced to the minimum; the consumption is reduced; the multi-end spinning with 24 ends / spinning positons can be realized; the economic benefit is increased; and the equipment production capacity is capable of meeting the market demands.

Description

technical field [0001] The invention relates to the technical field of chemical fiber machinery manufacturing, in particular to a heating roller drafting type high-Tron pre-oriented filament drafting and winding device. Background technique [0002] Polytrimethylene terephthalate (PTT) is a polymer formed by esterification and polycondensation of terephthalic acid (TPA) and 1,3-propylene glycol (PDO). It is a new type of polyester fiber. High Telun polymer has special properties due to its unique molecular structure and structure. The zigzag line structure of the high telon molecular chain makes the fiber have better advantages than polyester and nylon, that is, it feels softer, easier to care and dye, and has good color fastness to washing and anti-ultraviolet performance, acid resistance Alkali resistance, not easy to aging, good dimensional stability of the fabric. These advantages make Gaotelun fabrics have broad application prospects in the fields of new clothing and...

Problems solved by technology

As a result, the produced Cotton pre-oriented filaments have a large shrinkage rate, and the wound cake is prone to deformation during storage, sensitive to high temperatures during storage and transportation, and requires low spinning speeds , the storage period is short, and then, unwinding problems are prone to occur in the post-stretching and false-twisting deformation processing and production, such as: expansion deformation with hard edges, structural hardening and changes in filament properties, which seriously affect the post-stretching and false twisting Productivity and production quality in texturing
